Harnessing DNA molecules for disease detection and electronics

DNA molecules express heredity through genetic information. However, in the past few years, scientists have discovered that DNA can conduct electrical currents. This makes it an interesting candidate for roles that nature ...

New understanding of CRISPR-Cas9 tool could improve gene editing

Within a mere eight years, CRISPR-Cas9 has become the go-to genome editor for both basic research and gene therapy. But CRISPR-Cas9 also has spawned other potentially powerful DNA manipulation tools that could help fix genetic ...

Building better base editors

CRISPR-based gene editing has potential therapeutic benefits but also some technical shortcomings. One set of these gene editing tools, base editors, can rewrite the four individual DNA letters, or bases— A, C, T or G—which ...

A rapid, easy-to-use DNA amplification method at 37 Celcius

Scientists in Japan have developed a way of amplifying DNA on a scale suitable for use in the emerging fields of DNA-based computing and molecular robotics. By enabling highly sensitive nucleic acid detection, their method ...
